This is very cool! I love the feel of it but you're right the mouse is waaayyy too sensitive on web o.o I think the one thing that would be a game changer is if you could quickly remove lines of code rather than having to drag them (maybe if you could right-click them?). It just got a bit tedious because I sucked and couldn't do it on the first run haha :D Full round of applause for making this in one weekend though!
